Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

TV channel Identification using Linux C Programming
2 septembre 2013, par Aditya Suku RaghavI need to develop an application which will identify the channel name which is currently running in the Television. I am using Easy CaP Video capturing device to take the video in from the dth set top boxes. Currently i am used ffmpeg to cut it into frames . then i used Tesseract OCR to read the image contents. It does not seems to be perfect. So i need some other method to implement that. Can any one help me on implementing this application.

avfilter/af_headphone : Simplify parsing channel mapping string
27 août 2020, par Andreas Rheinhardtavfilter/af_headphone : Simplify parsing channel mapping string
When parsing the channel mapping string (a string containing '|'
delimited tokens each of which is supposed to contain a channel name
like "FR"), the old code would at each step read up to seven uppercase
characters from the input string and give this to
av_get_channel_layout() to parse. The returned layout is then checked
for being a layout with a single channel set by computing its logarithm.Besides being overtly complicated this also has the drawback of relying
on the assumption that every channel name consists of at most seven
uppercase letters only ; but said assumption is wrong : The abbreviation
of the second low frequency channel is LFE2. Furthermore it treats
garbage like "FRfoo" as valid channel.This commit changes this by using av_get_channel_layout() directly ;
furthermore, av_get_channel_layout_nb_channels() (which uses popcount)
is used to find out the number of channels instead of the custom code
to calculate the logarithm.(As a consequence, certain other formats to specify the channel layouts
are now accepted (like the hex versions of av_get_channel_layout()) ; but
this is actually not bad at all.)Reviewed-by : Paul B Mahol <onemda@gmail.com>

dcadec : set the output channel mode more accurately.
11 décembre 2013, par Tim Walkerdcadec : set the output channel mode more accurately.
When downmixing 2.1 to 2-channel, if the 2.0 portion is Lt/Rt, sum-difference or dual mono, the actual output will be the same (with the LFE either mixed-in or discarded).
Also, when downmixing an arbitrary layout to 2-channel, if the bitstream contains custom downmix coefficients targeting Lt/Rt, then the output will be Lt/Rt rather than regular Stereo.
